To all whom it may concern:

Be it known that I, FRANK H. BALL, cit;- zen of the United States, residing at North Plainfield, in the county ofSo-m State of New Jersey, haveinventednew and useful Improvements in Connections for Electric Conductors, of which the "following is a specification. I

his invention relates to connections for electric'conductors and consists in. certain im rovements in the construction thereof as be hereinafter fully described and pointed out in the claiins.

In some respects the invention is an improvement over the device shown by Fred erick 0. Ball, in the application filed January 31, 1906, No. 298,736. In the construction'therein shown, a olampjis formed by a 5 ring loop. Anelectric conductor is passed throu h one side of the 100 and is secured to the ot er side usually by so dering. The wire passing through the side of the spring loop makes itinconvenient to compress the spring 111 placing it on a conductor and the manner of secunng the flexible conductor to the clamp. is more expensive than that shown in the resent application.

The invention is illustrated in'the accc3npanying drawings as follows: I

Figure 1 shows two batteries connected with my connection. Fig. 2, a side elevation of the clamp forming part of the connection.

ig. 3 is a cross section of the same. Fig. 4, a plan view of an end of the flexible conductor. Fig. 5, an end view/of the same.

The connection is shown as applied to batterie's and it is peculiarly adapted for this purpose, but may be used wherever it is desirable to connect two conductors. The batteries A;A are of the usual form. a-a and b-b are the electrodes. The electrodes 0 are screw threaded and the electrodes 6 ave the screw threaded studs 5.

The clamp C is preferably in the form of a spring clamp; it comprising the turns, the sides 0 and the inwardly extending contact plates 0. The contact plates, preferably overlapped, are provided with perforations c". e perforations are so arranged that when the spring loop is compressed they are broughtinto register and while in register, a clamp may be placed over an electrode.

hen releasedthe spring acting on thia plates forces them into engagement with the threads of the electrodes. The loop has the contracted portion 0 and the flexible conduct st and itor D is placed in this contracted portion. I The flexible conductor has the o dinary ini sul tion (Z so that it is desirable to remove insulation from the end. (2 and wrap the wires back over the insulation as at (Z so that t ey may be brought into intimate contact 1 with the walls of the loop. The end of the conductor D, thus arranged, is forced into contracted portion c. This ordinarily holds it in place, but as an additional means of se curity, I force the point c inwardly into the material forming the conductor, thus making a positive engagement. The point e is arranged in the material forming the swing loop.

it will be observed that when the loop is compressed to brin the perforations into register, that the walls of the loop are forced inwardly, thus exerting a maximum pressure upon the flexible conductor when the clamp is in place on the electrode. This makes the engagement between the flexible conductor and the clamp stronger and also makes the electrical contact more certain while the connection is in use.

i What I claim as new is:

I 1. A connection for electric conductors comprising an electric conductor; a spring clamp having jaws actuated by detachably engage the conductor with a l spring pressed cont ct; and a second conductor clamped and permanently held by the jaws offthe clamp in position to receive greater pressure fiyom the jaws as the clamp in engagement with the first conl f is placed l ductor. I 2. A connection for electric conductors comprising a spring loop; devices at the ends of the loop for detachably engaging an electric conductor with spring ressure exerted by the loop; and a second e ectric conductor arranged in the loop and clamped by the walls thereof. I 3. A connection for electric conductors comprising a spring loop (levlces at the ends of the loop for detachably engaging an electric conductor; and a second electric conductor arranged in theloop and clamped by the walls thereof, the walls of the loop closing on the conductor therein as the clamp is brought to position to engage the conductor i at the ends of the loop. l 4 connetion for electric conductors comprising a siiring loop formed of the turn 6 and sides 0 haying contact plates 0 transversely of the sides of the loop arranged and has;

the clamp to the loop; and a ing contact surfaces along the edgbes thereof l comprising the that are forced into engagement y the action of the loop; and an electric conductor arranged within the loop and clamped by the walls thereof.

5. A.,connection for electric conductors comprising a spring clamp in the form of a loop and having overlapping ,lates extending inwardly from the loop, said plates being brought into register by the compression ofthe loop; and a conductor arranged within the loop and clamped by the walls thereof, the walls closing on the conductor as the clamp is sprung to position to bring the perforations into register.

7. A connection for electric conductors rovided with perforations adapted tobe.

eeeaoe flexible conductor D; a the form of a spring loop secured to each end of the flexible connection by the clamping action of the walls of the loop, the engaging pressure on the flexible connection being increasedas the clamps are compressed,

said clamps having 1aws adapted to engage clamp in an electric conductor when compressed.

8. A connection for electric conductors comprising the flexible conductor D and the clamp C, the clamp C being in the form of a spring loop having the turn 0, contracted portion 0, sides 0 extending from the por tion 0, and overlapping plates 0 extending from the sides having the perforations 0 the conductor D being arranged in the contracted portion '0 and clamped by the walls thereof.
